So the memory on my phone has been at 50mb or lower for the past few months. I've done the standard stuff that I know: clear cache, moved every freakin' app to the SD card, and still my memory stays low. Yesterday I got it to 50mb so the notification finally went away. I've been getting the "install new update" notice for a while so I finally backed up my data and updated to FC09. I re-rooted, then restored my data...memory down to 16mb now.

What do I need to do to get my phone memory to normal levels? And why is the memory so low if I have all moveable apps on the SD card (and the ones I can't move certainly don't total 450mb).
